There's a bug in your Firefox extension. In Firefox 5 and 6, the add-on bar can be closed and should stay closed until activated by the user, but when Elite proxy is installed, it always shows at start up. On the help pages it is suggested that this is caused by extensions that aren't fully compatible and after a test on a clean Firefox profile, this extension showed this bug.
add-on version 1.1.3, Windows 7 32-bit
